Hello everyone, long time lurker first time poster. I have a 2015 Jeep Wrangler with 120,000 miles and lately I have noticed that my oil pressure (as displayed in the EVIC) will jump up from 40-44psi to 65-75psi after about 10-45 min of interstate speeds of around 70mph. When this occurs my engine temperature will be between 215-222 degrees F. I am not experiencing a check engine light when this happens. I understand the oil pump of the 3.6L Pentastar is a 2 stage pump that will switch to high pressure mode after achieving 3500rpm and possibly other parameters. I know this is not normal, but my questions are what will happen if I continue to drive the vehicle with the oil pressure at this psi, what could be causing this issue, and how critical is it to get repaired. I use Pennzoil Ultra Platinum 5W-20 with WIX XP filters. I recently changed my oil and used a Mopar filter...the issue continues.
I have attached pictures of my dash when this occurs including oil pressure, engine temp, and ambient temp. Some of the pictures are blurry and I apologize.
